Aims: Though patients have been shown to have difficulties in achieving oral cleanliness after self-performed oral hygiene, scientifically and empirically justified standards for the degree of oral cleanliness they should achieve are lacking. Oral cleanliness of dental staff was therefore assessed as an indicator of what might be an upper limit of what can be expected by patients.
Materials And Methods: In a multicentre study, N = 64 university dentists, N = 33 dental students and N = 30 dental assistants were asked to perform manual oral hygiene to the best of their abilities.
Background: This study was conducted to assess plaque removal skills in patients with fixed dental prostheses (FDP), and effectiveness of computer-based training (CBT) of different brushing techniques (Fones versus Bass technique in their common modifications).
Methods: Ninety-three patients with FDP were randomly allocated to one of three training groups: 1) C (control group); 2) F (Fones technique group); and 3) B (Bass technique group). All patients received CBT of the basics of toothbrushing.
Aim: This study aims to assess plaque scores after oral hygiene in an unselected sample of young German adults and to compare the effects of computer-based training of the Fones versus the modified Bass technique on these scores.
Material And Methods: Seventy 18- to 19-year olds received computer-based training of the Fones technique, the modified Bass technique or basic instructions of oral hygiene alone (control group). The marginal plaque index (MPI; percentage of sections adjacent to the gingiva showing plaque) and BOP were assessed at baseline and after 6, 12 and 28 weeks.
Background: Brushing performance is an important factor for brushing success. Thus, observing brushing performance might help to explain deficits in oral hygiene. However, it is unknown how brushing behavior observed at one time relates to brushing capabilities observed at another time.

This study aims to develop a new marginal plaque index (MPI) and to assess its validity and treatment sensitivity compared to the internationally accepted Turesky modification of the Quigley and Hein Index (TQHI).
Methods: Data from two studies with n = 64 and n = 67 participants, respectively, are reported here.
Background: Gingivitis and other plaque-associated diseases have a high prevalence in western communities even though the majority of adults report daily oral hygiene. This indicates a lack of oral hygiene skills. Currently, there is no clear evidence as to which brushing technique would bring about the best oral hygiene skills.

Methods: Eighty-three students without clinical signs of periodontitis were randomly assigned to either a control group or one of three experimental conditions: 1) written instruction, 2) standardized oral instruction, or 3) individualized oral instruction. Plaque and bleeding indices were assessed to analyze intervention effects on oral health and oral hygiene skills.
